need an ID on an old gun now with pictures!

Hi!
I posted this question a while back with no pics but now I have some
This gun holds 7 shots and has a fold up trigger. My grandpa brought it back from WW2. It would be awesome if somebody could unravel the mystery of where this gun came from and who made it!

dont know much about folding trigger handguns, and im certainly no expert, but it's similar to this http://www.thefirearmsforum.com/showthread.php?t=52008 with different grips in better shape, and it's in a larger caliber, and it appears to be a bit fancier as well, someone who really knows should be around shortly to pin down its history, but thought id say something in the meantime

With the length of cylinder it is most likley 5.7mm,they also made them in 25acp,known as Velo-Dogs,sold to cyclists mainly in France to shoot dog that chased them.1900 to 1920 approx.If you can get a copy of Arms of the World 1911 by Digest Books inc Northfield Illinois, there are dozens of them listed,pics enc

Thanks for all the responses!
Where would I find this proof mark?
The only 2 markings that I saw on the gun that did not make it into the pictures were a 5 to 6 digit number and a very small 6 sided star stamped on the Cylinder and I think in another spot also, but I can't remember exactly (I will have to check with my Grandma again)

What caliber is it? I have one just like it. The topstrap is marked "F Faulkner & Cie Prague." On the left side of the barrel is "22. 11. 21." The number "2110" is stamped on the frontstrap of grip and the number "268" stamped on the top of the barrel. It is an 8mm five-shot with a loading gate, a 45mm barrel length (eight sided, unrifled) and a folding trigger. It can be fired double or single action and has a bird's-head grip. The overall length is about 150mm, and height is about 90mm. I will try to get pics of it up soon. Your's looks newer.
